What are the lightweight materials for automobiles?

Which domestic manufacturer of lightweight aluminum materials for automobiles is the best?

Automobile lightweighting is to reduce the weight of the entire vehicle as much as possible while ensuring the strength and safety performance of the vehicle, thereby improving the vehicle's power, reducing fuel consumption, and reducing exhaust pollution. At present, the utilization rate of aluminum alloy in transmission cases and heat exchange systems is close to 100%, and engine blocks, cylinder heads, and wheels have also reached a high level. In the future, we will focus on expanding parts such as body and chassis. With the advancement of technology, the application of aluminum alloys in wheels, engines, radiators, oil pipes, etc. will gradually deepen. With the entry of aluminum profiles and aluminum parts finishing technology, the aluminum alloy parts used in new energy vehicles have gradually expanded to include body, wheels, chassis, bumper anti-collision beams, floors, electric batteries, energy-absorbing boxes, foot pedals, and sunroof sliders. rails, overhead luggage racks and seats.

Today, let us take stock of the leading companies in various fields of the domestic automotive lightweight aluminum manufacturing industry.
